And thus we get to SpaceVidCast, which, in partnership with Ustream, has the one of the few HD feeds of tonight's launch of the Space Shuttle Endeavour - press the play button below to start the stream.

NASA has been embracing social media for a while now - just look at how Astronaut Mike Massimino has used Twitter and live video and the tweets of the Mars Phoenix Lander. And since I am a huge space enthusiast (I was at one time a Physics and Astronomy major, after all), this type of live streaming implementation excites me.

Now we just need to have the astronauts use Ustream...in space!!! In the meantime, get your space exploration fix by watching the shuttle launch with us. Blast off is scheduled for 7.14pm ET:
